I'm sure they'd want it open by Holliday time, so early Decemeber or late Novemeber is likey. December first as said above is when it will probably open. Hope I helped.
I believe it is still very much up in the air. My guess is if everything goes well it will be open (at least soft opening) earlier then that. If things don't go well...anybody's guess! Remember it was Test Track that opened up 18 months after the initial opening date. I suspect that they gave themselves some wiggle room this time, but it's hard to tell what goes through the mind of mice-men!
